721201 Description

Description for Experiment 721201

The objective of this experiment is to determine the effect of amount of ground cover on the spectral response of corn as influenced by the soil background. Russell silt loam and Chalmers silty clay loam soils were chosen as they are common soils of northern Indiana. This experiment was designed by Dr. M. Bauer and Dr. J. Cipra of the Laboratory for Applications of Remote Sensing, Purdue University.

The experiment was conducted on the Purdue University Agronomy Farm in the summer of 1972. Corn (Zea mays L.) were grown in the plots 6-76 cm rows, 4.6 meters long on May 25, 1972. Fertilizer and herbicides were applied prior to planting. The rows were marked by tractor and planting was done by hand in order to obtain the desired spacing between plants. Plots with varying amounts of ground cover were established by having five different plant populations: 0, 15, 30, 60 and 90 thousand plants per hectare, each plant population being replicated twice.
